tiledlayout(m,n)
tiledlayout('flow')
tiledlayout(___,Name,Value)
tiledlayout(parent,___)
t = tiledlayout(___)

explain

tiledlayout(m,n) Create a block diagram layout , Used to display multiple drawings in the current drawing window . The layout has fixed m×n Block arrangement , Up to m*n Plots . If there is no picture window ,MATLAB A drawing window will be created and the layout will be placed in it . If the current drawing window contains an existing coordinate area or layout ,MATLAB It will be replaced with a new layout .

A block diagram layout contains an invisible block grid that covers the entire window or parent container . Each block can contain a coordinate area for displaying the drawing . After creating the layout , call nexttile Function to place the coordinate area object into the layout . Then call the drawing function to draw in the coordinate area .

tiledlayout('flow') Specify the layout 'flow' Block arrangement . first , Only one empty block fills the entire layout . When you call nexttile when , The layout will be adjusted as needed to adapt to the new coordinate area , At the same time, keep the aspect ratio of all blocks about 4:3.

tiledlayout(___,Name,Value) Use one or more names - Value specifies other options for the layout for the group parameter . Please specify these options after all other input parameters . for example ,tiledlayout(2,2,'TileSpacing','compact') Create a 2×2 Layout , The minimum spacing between blocks . About the attribute list , see also TiledChartLayout attribute .

tiledlayout(parent,___) Create a layout in the specified parent container instead of in the current drawing window . Please specify the parent container before all other input parameters .

t = tiledlayout(___) return TiledChartLayout object . After creating the layout , Use t Configure the properties of the layout .

Example

establish 2×2 Layout

Create a 2×2 Block diagram layout , And call peaks Function to get the coordinates of the predefined surface . By calling nexttile function , Create a coordinate area object in the first block . And then call surf Function to plot in the coordinate area . Repeat the process for the other three blocks using different drawing functions .

tiledlayout(2,2);
[X,Y,Z] = peaks(20);

% Tile 1
nexttile
surf(X,Y,Z)

% Tile 2
nexttile

Then draw in the first block y1. The first figure fills the entire layout .

x = linspace(0,30);
y1 = sin(x/2);
y2 = sin(x/3);
y3 = sin(x/4);

load patients Data sets , And create a table based on a subset of variables . And then create a 2×2 Block diagram layout . Display the scatter plot in the first block , Show the heat map in the second block , And display the stacking diagram across the bottom two blocks .

load patients
tbl = table(Diastolic,Smoker,Systolic,Height,Weight,SelfAssessedHealthStatus);
tiledlayout(2,2)

% Scatter plot
nexttile
scatter(tbl.Height,tbl.Weight)

% Heatmap
nexttile
heatmap(tbl,'Smoker','SelfAssessedHealthStatus','Title','Smoker''s Health');

% Stacked plot
nexttile([1 2])
stackedplot(tbl,{'Systolic','Diastolic'});

As shown in the figure ：

call nexttile, And assign the block number as 1 So that the coordinate area in the block becomes the current coordinate area . Replace the content of the block with a scatter histogram .

As shown in the figure ：

Show the shared color bar in a separate block

When you want to share a color bar or legend between two or more diagrams , It can be placed in a separate block . Create in the block diagram layout peaks and membrane Filled contour map of dataset .

Z1 = peaks;
Z2 = membrane;
tiledlayout(2,1);
nexttile

cb = colorbar;
cb.Layout.Tile = 'east';

As shown in the figure ：

Manually create and configure coordinate areas

Sometimes , You may need to manually create the coordinate area before calling the drawing function . When creating the coordinate area , Please put parent The parameter is specified as the block diagram layout . Then set the coordinate area Layout Property to locate the coordinate area .

Create a block diagram layout t And designate 'flow' Block arrangement . Display a plot in each of the first three blocks .

t = tiledlayout('flow');
nexttile
